Connecting up the PPA to a signal Generator
A signal generator is required to provide a 1.41V PK (1.00Vrms) 50Hz sine wave, if
the signal generator expects a 50Ohm load impedance then an output voltage of
0.707V (0.5Vrms) should be used. This signal is used for checking the integrity of
the external voltage and external current inputs; these are 3Vpk Max Isolated
Differential Voltage inputs.
The PPA is connected to the signal as shown in the drawing. The various modes on
the instrument can then be selected. The following section provides screenshots of
the PPA display for each of these modes.
To make the connections shown in the diagram you will need the following
accessories that are not supplied with the PPA.
4 x BNC cables for connections on the rear of the PPA.
2 x BNC cables to connect between the PPA and the signal generator.
5 x BNC “T” piece connectors.
